The commission of Jack on selling house is $7552.9.

Given that, Jack make on the sale of a $160,700 house if he receives 4.7% of the selling price.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Let commission of Jack be x.

Now, x= 4.7% of 160,700

⇒ x = 0.047 × 160,700

⇒ x = 7552.9

Therefore, the commission of Jack on selling house is $7552.9.

The cuboid is a solid-shaped figure formed by six faces. A cuboid is a simple figure. It has three dimensions - width, length, and height. Thus, the cuboid is a parallelepiped. Now, the surface area of the parallelepiped is the sum of the areas of all sides, that is:

where

l is the lenght

w is the width

and

h is the height

According to the figure given in the problem, we have that:

The x–intercept of g(h(x)) is the option;

[tex] \displaystyle {-\frac{2}{3}}[/tex]

The x–intercept of a function is given by the point where the function intersects the x–axis.

From the given table, the slope of the graph of g(x), [tex] m_1 [/tex] is given by the equation;

[tex] \displaystyle{ m_1 = \frac{ - 4 - ( - 8)}{ - 4 - ( - 6))} = \frac{4}{2} = 2}[/tex]

The equation of g(x) in point slope form is therefore;

g(x) - (-4) = 2×(x - (-4)) = 2•x + 8

g(x) = 2•x + 8 - 4 = 2•x + 4

g(x) = 2•x + 4

The slope of the function h(x), [tex] m_2 [/tex] is found using the equation;

[tex] \displaystyle{ m_2 = \frac{ 8 - 14}{ - 4 - ( - 6))} = \frac{ - 6}{2} = - 3}[/tex]

h(x) presented in point and slope form is therefore;

h(x) - 8 = (-3)×(x - (-4)) = -3•x - 12

h(x) = -3•x - 12 + 8 = -3•x - 4

h(x) = -3•x - 4

g(h(x)) = 2•h(x) + 4

Plugging in the value of h(x) gives,;

g(h(x)) = 2×(-3•x - 4) + 4 = -6•x - 8 + 4

g(h(x)) = -6•x - 4

The x–intercept of g(h(x)) is given by the point where g(h(x)) = 0, which gives;

At the x–intercept, g(h(x)) = 0 = -6•x - 4

[tex] \displaystyle{ x = \frac{4}{-6} = -\frac{ 2}{3} }[/tex]

The x–intercept is [tex] \displaystyle{ -\frac{ 2}{3} }[/tex]

We are given the percentages for males on the left side and the percentages for females on the right side.

We are trying to find four groups that make up nearly 1/2 of the male population, so we want the percentages for these groups to add up to nearly 50%.

Let's take a look at the lowest age groups of the male population, which in turn make up the highest proportion of the male population.

We have the age group 0-4, which makes up roughly 12%.

We have the age group 5-9, which makes up roughly 11%.

We have the age group 10-14, which makes up roughly 11%.

We have the age group 15-19, which makes up roughly 12.5%.

If we add all of these percentages together, we get:

12% + 11% + 11% + 12.5% = 46.5%

Since we cannot go any smaller than 46.5% because this is the closest percentage to 50%, the four groups that make up nearly one half of the male population must be:

Ages 0-4, 5-9, 10-14, and 15-19

Applying the definition of the adjacent angles of a trapezoid, the value of x in quadrilateral TUVS is: x = 4.

The adjacent angles of a trapezoid are the angles that are found on the same leg of the trapezoid, and they are said to be supplementary to each other because they have a sum of 180 degrees.

Given that quadrilateral TUVS is a trapezoid, where angles SVU and TSV are adjacent angles, therefore:

m∠SVU + m∠TSV = 180°

m∠SVU = 139°

m∠TSV = (14x - 15)°

Substitute

139 + (14x - 15) = 180

139 + 14x - 15 = 180

Combine like terms

124 + 14x = 180

14x = 180 - 124

14x = 56

14x/14 = 56/14

x = 4

The roots of an equation is "solutions" of the equation. Solutions are the numerical values equal to the variable after solving it.

To determine the sum and product of the roots of a quadratic equation, the equation has to be written in the form ax²+bx+c = 0

From that form, the sum of the roots is given by -b/c and the product is c/a

For example, we want to find the sum and product of the roots of the quadratic equation 3x²-x = 2

Notice that the equation is not written in the form described above. So, it has to be written as 3x²-x - 2 = 0

From this form, we see that  and a = 3, b = -1 and c = -2

Therefore, the sum is -b/a = 1/3  while the product is c/a = -2/3 = -2/3

The table and graph given show the information about two national parks.

It is required to find the rate of change of the population of the two parks between 2009 and 2014, and then determine the park that shows faster population growth during those years.

Notice that the variable x represents the number of years after 2005.

Hence, the years 2009 and 2014 represent, x=4 and x=9, respectively.

The formula for the rate of change of a function f(x) between x=a and x=b is given by the formula:

Calculate the rate of change for park A:

Substitute a=4 and b=9 into the formula:

Substitute f(9)=2870 and f(4)=2370 from the table for park A into the expression for the rate of change:

Calculate the rate of change for park B:

Substitute f(9)=2800 and f(4)=2200 from the graph of park B:

Notice that the rate of change in population for park B is higher than that of park A.

Hence, park B showed faster population growth during those years.

Answers:

Rate of change for park A= 100 swallows per year.

Rate of change for park B= 120 swallows per year.

Park B showed faster population growth during those years.

Recall that when two angles add to give 90 degrees, they are called "complementary angles" This is the case here where you are adding an unknown angle to one that measures 51 degrees to obtain a right angle (90 degrees)

The unknown angle (?) is called the "complementary angle to the 51 degree one.

Please select the third option :

C. Complementary.

Do you remember how it looks an angle that measures 90 degrees? It looks like the angle formed by a square edge, or by two lines that are perpendicular to each other.

When you have two angles one in contact (adjacent) to the other and the two together complete a right angle , those two angles are called complementary angles. There is nothing profound to derive from that, but that it is simply a definition.

r = ( 6 X 194 - 21 X 43 ) / √[ {6 X 91 - (21)²}{ 6 X 483 - (43)²}]

r = ( 1164 - 903) / √( 546 - 441)(2898 - 1849)

r = 261 / √ 105 X 1049

r = 261 / √110145

From the graphs we can conclude:

Triangle BCD is similar to triangle EFG.

The behavior of the function is given as follows:

A function from a set X to a set Y allocates precisely one element of Y to each element of X. The set X is known as the function's domain, while the set Y is known as the function's codomain.

End behavior of a function f defines the behavior of the function's graph at the "ends" of the x-axis. Said differently, the end behavior of a function explains the graph's trend when we look at the right end of the x-axis (as x approaches +∞) and the left end of the x-axis (as x approaches -∞).

Using the normal distribution and the central limit theorem, it is found that the probabilities are given as follows:

24. Single person has an IQ score above 105: 0.3694.

25. Sample mean (55 people) above 105: 0.0067.

The z-score of a measure X of a variable that has mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by the rule presented as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The mean and the standard deviation of IQ scores are given as follows:

[tex]\mu = 100, \sigma = 15[/tex]

The probability that a single person has an IQ score higher than 105 is one subtracted by the p-value of Z when X = 105, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (105 - 100)/15

Z = 0.33

Z = 0.33 has a p-value of 0.6306

1 - 0.6303 = 0.3694.

For the sample of 55, the standard error is:

[tex]s = \frac{15}{\sqrt{55}} = 2.02[/tex]

Hence:

[tex]Z = \frac{X - \mu}{s}[/tex]

Z = (105 - 100)/2.02

Z = 2.48

Z = 2.48 has a p-value of 0.9933.

1 - 0.9933 = 0.0067.
